Data flow: Receiving email on an iOS device using the BlackBerry Secure Gateway
iOSdevice using the
BlackBerry Secure Gateway
This data flow describes how work email and calendar data travels between
iOSdevices and the
Exchange ActiveSyncserver using the
BlackBerry Secure Gateway.
- The device issues an HTTPS request to the mail server and requests that the mail server notify the device when any items change in the folders that are configured for synchronization. The request travels through the encrypted and authenticated channel between theBlackBerry Infrastructureand theBlackBerry Secure Gatewayto the mail server.
- If there are no new or changed items during this interval, the mail server sends an "HTTP 200 OK" message to the device. The device issues a new request and the process starts over.
- When there are new or changed items for the device, such as a new email or updated calendar entry, the mail server sends the updates to the device through the secure channel between theBlackBerry Secure Gatewayand theBlackBerry Infrastructureto the email or organizer app on the device.
- When the synchronization is complete, the device issues another request to restart the process.
